Typedefs

- typedef void \*Snpe\_ITensor\_Handle\_t

    - Represents a tensor which holds n-dimensional data. It is important to understand how the tensor data is represented in memory relative to the tensor dimensions. Tensors store data in memory in row-major order (i.e. the last tensor dimension is the fastest varying one). For example, if you have a two dimensional tensor with 3 rows and 2 columns (i.e. the tensor dimensions are 3,2 as returned in tensor dimension vectors) with the following data in terms rows and columns:

| 1 2 |

| 3 4 |

 | 5 6 | 

This data would be stored in memory as 1,2,3,4,5,6.

    - Destroys/frees an ITensor

- Parameters

    - **userBufferHandle** – **[in]** : Handle to access the IUserBuffer

- Returns

    - SNPE\_SUCCESS if Delete operation successful.

- void \*Snpe\_ITensor\_GetData([Snpe\_ITensor\_Handle\_t](https://docs.qualcomm.com/doc/80-63442-10/topic/c_api-rst_file_DlSystem_ITensor_h.html#_CPPv421Snpe_ITensor_Handle_t) tensorHandle)

    - Returns a tensor iterator pointing to the beginning of the data in the tensor.

- Parameters

    - **tensorHandle** – **[in]** : Handle to access ITensor

- Returns

    - The tensor data as a void pointer.

    - Gets the shape of this tensor.

The last element of the vector represents the fastest varying dimension and the zeroth element represents the slowest varying dimension, etc.

- Parameters

    - **tensorHandle** – **[in]** : Handle to access ITensor

- Returns

    - A TensorShape handle holding the tensor dimensions.

- size\_t Snpe\_ITensor\_GetSize([Snpe\_ITensor\_Handle\_t](https://docs.qualcomm.com/doc/80-63442-10/topic/c_api-rst_file_DlSystem_ITensor_h.html#_CPPv421Snpe_ITensor_Handle_t) tensorHandle)

    - Returns the element size of the data in the tensor (discounting strides). This is how big a buffer would need to be to hold the tensor data contiguously in memory.

- Parameters

    - **tensorHandle** – **[in]** : Handle to access ITensor

- Returns

    - The size of the tensor (in elements).
